| Abstract: | An overall computation and analysis was made of the pylon, and the impact of main girder longitudinal and transverse elastic confinement on the dynamic property and earthquake response of the main bridge, including establishment of computation model, computation of dynamic property, and analysis of earthquake response. Computation result indicated that elastic confinement for operation and the float system for earthquake have high aseismic performance. |
